Ridley Noah RS CR1 Road Bike - 2014

If you like to go fast, you'll need strength, stamina, and a bike that gives you every performance advantage possible. The first two you'll have to get yourself. But when it comes to performance advantages, no one can deliver like Ridley.

To get an edge on the best sprinters in the world, Andre Griepel of Lotto-Belisol worked with Ridley to design the most advanced sprinter's bike in the world. The result was the Ridley Noah. With raindrop-shaped aerofoil tubing, integrated FAST fork and surface finishing technology, and the stiffest construction you'll find anywhere, the Noah is a bike that's built for one thing: speed. The Noah RS is a high-speed, low-drag frame created from a perfect blend of 24-ton*, 30-ton, and 40-ton carbon fibers for the ultimate in stiffness and responsiveness. By using three different carbon blends, the bike has immense strength and stiffness in high-stress areas, but is also compliant enough in areas like the seatstays to make the ride comfortable without beating up the rider. The aero carbon fiber tubes use shapes determined by nature.

By necessity, the most aerodynamic shape found in nature is the rain drop. Water is a malleable but incompressible substance, so as a rain drop falls and reacts to air drag, it is able to achieve the most efficient shape possible. Ridley engineers reasoned that if it works for water, it'll work for a bike. The aero-shaped tubing found on the Noah, when combined with their revolutionary FAST Concept innovations (more below), makes it one of the fastest bikes in the pro peloton...or your local group ride.

The Fast Concept F-Surface treatment further enhances the aerodynamic properties of the frame. When you ride a bike, frontal wind has to "pass around" the tubes of the bike. Basically, you're forcing the air to conform itself to the shape of the rider and the bicycle. In some areas, the air "releases" from the bike, creating drag and costing you speed. The F-Surface concept was developed from Ridley's wind tunnel testing, and identified areas of the bike where this release happens. Using special surface treatments at strategic locations, F-Surface results in a smoother flow of air over the bike, for more aero efficiency and more speed.

The Noah RS also features the full carbon fiber F-Splitfork fork design that has a dramatic impact on drag reduction. Most of the air turbulence created by the bike is caused by the wheels and spokes. At the top of the wheels, the spokes are moving forward while colliding with the air, causing turbulence, which causes drag, which causes you to lose speed. To solve this problem, Ridley engineered a split channel into the fork arm. The Ridley Splitfork guides the incoming frontal air away from the wheel and spokes, resulting in a 7.44% reduction in drag. In fact, the Splitfork works so well that aerodynamic efficiency actually increases as you ride faster.

The Noah RS also features internal cable routing, and for all the right reasons. Internal cable routing not only keeps the lines of the bike cleaner & makes the frame more aerodynamic, but it also cuts down on cable slap and fouling--essential for enhanced performance. It also helps keep the cables from wearing out prematurely, & keeps them cleaner for smoother, more precise shifting and braking in any weather conditions.

Additionally, a PF30 bottom bracket and oversized, tapered headtube enhance frame stiffness. The PF30 bottom bracket allows the use of a crankset with a shorter, beefier spindle for less flex and improved power transmission. The bottom bracket shell is also burlier, which means that the frame is stiffer, so more watts go into forward movement, and less into frame flex. The tapered headtube enables the frame to be stiffer for improved handling and control on even the roughest terrain.

The Ultegra 6800 components are more than just an 11-speed evolution of Ultegra 6700. The new Ultegra features newly redesigned ergonomic hood and lever shapes that draw inspiration directly from the company's superlative Di2 systems. The result is a more comfortable lever that requires less force to execute a shift, thanks to decreased cable friction and improved housing. Ultegra 6800 also features a fundamental redesign of the front derailleur, with a longer lever arm for more effective and precise front shifts. The rear derailleur has also been redesigned to be lighter and more responsive, making shifting across the entire cassette feel easy and snappy, with no chain rubbing or hesitation. And, of course, there is the revolutionary new 4-arm design crankset. The new Shimano design is a fundamental rethink of how forces are distributed across the crankset spider. The result is a stiffer crankset, stiff rings, and--most importantly-- one BCD measurement for all chainring sizes, so you no longer have to choose between race or compact.

Rounding out this impressive package is a build kit from Ridley's own 4Za brand. 4Za is in many ways unlike some other company's house brand component arms. Ridley engineers every 4Za component to integrate seamlessly with their bikes at a basic level, ensuring optimized performance at every level. In fact, 4Za is the trusted component supplier of Lotto-Belisol, who chose not to pursue a component supplier like FSA or 3T in favor of 4Za. The bike rolls on a set of lightweight Fulcrum Racing Quattro clinchers, which spin up quickly, climb like they mean it, and deliver superb braking performance.
